Phytochemical Composition and the Evaluation of Antioxidant Activity of Methanolic Extract and Essential Oil of Satureja Rechingeri Extract and Essential Oil

Abstract

Aromatic herbs have special applications in pharmacy and cosmetics due to their secondary and medicinal compounds. For this reason, aromatic plants are especially suitable for multifunctional sustainable crop models. The main purpose of this study was to evaluate of chemical compounds of essential oils in different organs of Satureja rechingeri belongs to Asteraceae family. The plant was collected and then dried in the shade for a month at room temperature. Essential oils were extracted by hydro distillation and were analyzed by GC-MS apparatus. The results of this study showed that the different organs can be effective in main compounds of essential oils. Antioxidant efficacy of extract and essential oil of S. rechingeri was determined by DPPH method. The most important compound identified in of S. rechingeri essential oil was carvacrol, which was found to be 83.90%, 81.11% and 95.70% in the leaves, flowers and stems of this plant, respectively. The results of the present study showed the antioxidant activity of methanolic extract of the plant. This is probably due to the presence of flavonoid and polyphenolic compounds. Satureja essential oil showed moderate antioxidant activity of S. rechingeri extract had stronger antioxidant effects compared with its essential oil. Therefore, S. rechingeri extract can be useful in food hygiene and medicine.
